How to reply to message with mention anywhere in guild with embed

[qyczq]

I tried something like this but it doesn't work

client.on('messageCreate', async (message) => {
    if(message.mentions?.repliedUser.id == client.user.id) {
        const embed = new WebEmbed()
            .setColor(0x00D003)
            .setDescription('description')
            .setTitle('title')
        message.reply({
            content: `${embed}`,
            fetchReply: true
        }).then((message) => console.log(`Reply sent`))
    }
})

Error:

    if(message.mentions?.repliedUser.id == client.user.id) {
                                    ^

TypeError: Cannot read properties of null (reading 'id')

I'm pretty sure you cannot get the replied user.
You need to fetch the message from message.reference.id and then make checks.

This is what I am doing for my bot:

let ref = message.channel.messages.cache.get(message.reference.messageId);
if (ref?.interaction?.user?.id !== client.user.id) return;

// logic

This works perfect and its shorter

client.on("messageCreate", (message) => {
    if (message.mentions.has(client.user.id)) {
        message.reply({
            content: 'Why the f you ping me',
        }).then((message) => console.log(`Reply sent`))
    }
})

I'm glad you've found a working answer, but I warn you this does not have a guild ID.
If you are targeting a guild, as you implied in the original post, you can check it in the if statement:

if (message.mentions.has(client.user.id) && message.guild.id === 'GUILD_ID')
